Yours appears to have a pilot fuel screw with a flexible extension on it (item you point to in the second picture), so that makes it quite a bit simpler to access. The black knob in the first pic is the idle speed adjustment only.

Thanks a lot help a lot on the backfiring

Very very much thanks!!!!!
